Back to Diabetes Basics NovoLog (Insulin Aspart)


NovoLog Vial NovoLog® (insulin aspart) is a rapid-acting human insulin analog sold by Novo Nordisk. NovoLog starts to work almost immediately, compared to Regular insulin which requires about 30 minutes to begin to work. Thus NovoLog can be injected right before a meal, or even immediately after a meal. For parents of children with diabetes who are picky or unpredictable eaters, NovoLog might be just the tool to help match the insulin given to the food eaten.

In addition to working faster, NovoLog has a shorter duration of action than Regular insulin. This means that people who use NovoLog might experience fewer night-time low blood sugars, and need to eat less for their mid-morning and mid-afternoon snacks. It also means that people who use NovoLog might need to increase their long-acting insulin (NPH or Ultralente for example) a little to compensate for the absence of the trailing action of Regular insulin.

NovoLog is taken in the same amount as Regular insulin. It can be mixed with NPH, but has not been tested with crystalline zinc insulins such as Lente and Ultralente and therefore should not be mixed with them. NovoLog is available in 10ml vial and 3ml cartidges. Like other insulin analogs, a prescription is needed for NovoLog in the US. Outside the United States, NovoLog is sold as NovoRapid®.
